Making a Cold Start
Use this feature to locate your position correctly, if the GM-120 is unable to
identify your position after being powered on for a few minutes. This may
happen if there is old, incorrect data in the device and the signal strength is
poor due to uneven distribution of the satellites. In some cases, you may
also wish to acquire fresh information from the satellites and clear the
previous, obsolete data from the memory.
The Cold Start feature enables you to restart navigation by acquiring fresh
positioning information from the available satellites as follows:
1. Press the Menu button twice to display the main
menu.
2. Scroll to the Cold Start option and press OK. The
device starts acquiring fresh satellite information.
Resetting to Factory Defaults
When strange encoding appears on the screen, restore all setting to factory
default to acquire fresh information from the satellites and clear the
previous, obsolete data from the memory.
To reset all settings to factory defaults:
1. Press the Menu button twice to display the main
menu.
2. Scroll to Satellite and press OK to enter the
satellite page.
3. Press and hold Menu and OK buttons for three
seconds. A warning message appears to confirm
resetting to factory defaults.

your reference.
Troubleshooting
Problems
I pressed the power
button but the
device doesn’t
switch off.
The unit does not
respond when I try
to move the cursor.
What do I do to
return to my current
position on the map
page after I have
moved the map?
Possible Solution
• Make sure that you hold the power button for
two seconds to turn it off.
• If the unit still doesn’t turn off, remove the
battery or the power source for five seconds
and install it again.
The map position may be latched. Check if the ▲
symbol is shown in the bottom right corner of the
map page. If so, press and hold a direction key to
unlatch the device.
Check if the ▲ symbol is showing in the bottom
right corner of the map page. Press the ESC
button to return to your current position.
• Make sure that you are not in simulation mode.
• Make sure you are in an area with no
obstruction such as trees or tall buildings.
The GM-120 fails to
locate my current
position.
• The GM-120 requires synchronization with at
least three satellites to identify with your
current location. Once the position has been
identified, it requires at least one satellite to
maintain status. If available satellite signals are
too low in orbit or all in a line, it may not be
able to locate your current location.
